《朝花夕拾》2024中考复习热点试题(解析版)

《朝花夕拾》2024中考复习热点试题(解析版)1.(2023·广西贺州·二模)读书,就是一场说走就走的旅行,班级将开展“跟着书本去旅行”的主题班会,请你积极参与。
(1)线路设计。
精读一篇课文,就好似沉浸在一场精彩的身心之旅中,将来若能身临其境,必有不同寻常的游览体验。
请你仿照示例,从我们所学的课文中选出两篇,设计两条“旅行”线路,领略旅行之美、探寻文化魅力。
示例:《故乡》——走进鲁迅故里绍兴,领略江南水乡美景和民风民俗。
线路一:线路二:(2)名著之旅。
本次的名著阅读之旅活动将从以下几个主题开展,请你根据自己的阅读经历,参照示例,完善下面的阅读推荐表。
阅读推荐主题书目作者推荐理由红色之旅①埃德加·斯诺实地采访,探寻红色中国的秘密②《朝花夕拾》③旧事重提,回忆成长历程光明之旅《艾青诗选》艾青④(3)探讨感悟。
论学习形式。
研学是一种将“研究性学习”和旅行体验相结合的校外教育活动,它日益成为当下一种常见的学生学习的方式。
在班会上,同学们就“研学”这一话题,各抒己见,以下是一位同学的看法,请你对此观点进行反驳,要求观点明确,有理有据,字数80字以内。
研学没有意义。
首先,学校教育可以帮助学生构建完整的知识体系,它是学生获取知识的主阵地;其次,研学只是一种旅行,学生很难从中获取真正的知识。
所以,学校没必要开展研学活动。
【答案】(1) 《壶口瀑布》——来到黄河中游,感受黄河的汹涌奔腾,声震天地。
《苏州园林》——走进苏州园林,欣赏亭台轩榭的艺术之美。
(2) 《红星照耀中国》追忆之旅/成长之旅鲁迅意象丰富,追求光明与正义/感情充沛,对祖国与人民的热爱(意对即可)(3)示例:研学非常重要。
学习不仅指学习书本知识,世间万物皆可学,研学会让我们的人生更丰富多彩;其次,在实践中学习,研学可以让学习变得更加生动有趣。
因此,我们应大力倡导研学。
【详解】(1)考查课文内容理解和仿写能力。
解答时,结合课文内容进行表达,且句式要和示例一致。

People hurried along the streets, trying to find shelter from the cold.Among them was a young man named Jack, who was (3)_his way to the subwaystation.As Jack approached the entrance, he noticed a small, shivering figure huddled in the corner. It was an old woman, (4)_in thin clothing. Without hesitation, Jack took off his coat and (5)_it around the old woman’s shoulders.(A)fiercely(B)gently(C)slowly(D)happily(E)making(F)taking(G)heading(H)driving(I)dressed(J)wearing(K)putting(L)having(M)wrapped(N)tied(O)put(P)hungAnswers:(1)A(2)C(3)B(4)A(5)AExplanation:(1)The wind was blowing fiercely, indicating the severity of the winterweather.(2)Jack was heading his way to the subway station, using the verb “head”to describe the direction of his movement.(3)The old woman was dressed in thin clothing, using the past participle“dressed” to describe her state of attire.(4)Jack wrapped his coat around the old woman’s shoulders, using the verb“wrapped” to describe the action of covering her with the coat.(5)There is no suitable option for the first blank as it is part of theintroduction and does not require a fill-in-the-blank response.四、语法填空题(本大题有10小题,每小题1分,共10分)1.Question:The book,____I bought last week, is very interesting.Answer: whichExplanation: This sentence requires a relative pronoun to link the two clauses. The non-defining relative clause “I bought last week” provides additional information about the book, but is not essential to defining the book itself. Therefore, we use “which” to introduce the clause.2.Question:She____her homework before dinner, but she forgot to turn it in.Answer: had doneExplanation: The context suggests that the action of doing homework occurred before the action of forgetting to turn it in, which in turn happened before dinner. This calls for the past perfect tense, which is used to indicate that an action happened before another past action. “Had done” is the correct form of the past perfect tense for the verb “do.”3、______ is well known to us all is that the old scientist, for______life was hard in the past, still works very hard in his eighties.A. As; whomB. What; whoseC. It; whoseD. What; whomAnswer: DExplanation: The first blank is a subject clause, which should be guided by a connective word that can serve as a subject. “As” can guide subject clauses, but it cannot be used at the beginning of a sentence as a subject. “It” is often used as a formal subject to replace the real subject clause at the end of the sentence, but in this sentence, the real subject clause is “that theold scientist, for______life was hard in the past, still works very hard in his eighties”, which is too long to be placed at the end. Therefore, “What” is the appropriate choice here, as it can serve as both a connective word and a subject.The second blank is a case where we need to determine the correct preposition for a non-restrictive attributive clause. The clause “for______life was hard in the past” modifies “the old scientist”. Since “life” belongs to “the old scient ist”, we need a possessive pronoun. “Whose” is the possessive form of “who”, indicating the possessor of something. Here, “whom” is not suitable because it is an object pronoun, not a possessive pronoun.4、_____ in the mountains for a week, the two students were finally saved by the local police.A. Having been lostB. To be lostC. Being lostD. LostAnswer: AExplanation: The phrase “_____ in the mountains for a week” is an adverbial clause of time, describing the state of the two students before they were saved. We need to determine the correct form of the verb “lose” to fit this context.Option A, “Having been lost”, is the present perfect participle form of the passive voice. It indicates that the action of being lost happened before the main action (being saved) and has a passive meaning, which fits the context perfectly.Option B, “To be lost”, is the infinitive form with the passive voice tobe. It usually expresses purpose or intention, which is not relevant here.Option C, “Being lost”, is the prese nt participle form of the passive voice. It describes an ongoing action or state, but since the students were no longer lost when they were saved, this option is not suitable.Option D, “Lost”, is the past participle form of the verb “lose”, but it is usually used as an adjective here. However, when used as an adjective, it does not indicate the timing of the action (before being saved) as clearly as the present perfect participle form. Therefore, “Having been lost” is the most appropriate choice.5、The book I borrowed from the library last week________(return) to me yet.Answer: hasn’t been returnedExplanation: 本题考查时态和语态。
